Description

Technical Field

[0001] The invention relates to the technical field of lithium battery processing, and in particular to a lithium battery processing and assembling device. Background Art

[0002] Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and uses non-aqueous electrolyte solutions. Lithium ion batteries do not contain metallic lithium and are rechargeable. Lithium ion batteries are widely used due to their own characteristics, including the automotive field, electric bicycles, etc., where lithium ion batteries are indispensable.

[0003] A Chinese patent with patent announcement number CN216648385U discloses a lithium battery assembly device, including a workbench and a first cylinder, a detection chamber, a first adjustment rod and a second adjustment rod are fixedly installed on the top of the workbench, a first cylinder is fixedly installed on the top of the detection chamber, and a pressure plate is fixedly installed on one end of the output shaft of the first cylinder. The advantage of this patent is that by placing the assembled lithium battery on the top of the conveyor belt, the conveyor belt moves, when the lithium battery passes through the first group of infrared sensors, if the height is inconsistent, it will block the infrared sensor from irradiating the laser on the sensor sheet, and then the lithium battery group moves to the bottom of the first cylinder, the operation of the first cylinder drives the pressure plate to descend and press the lithium battery down, and the second detection is performed by the second group of infrared sensors. The device can detect and repair lithium batteries that are not assembled well, which can greatly improve the quality of the lithium battery group.

[0004] However, the current assembly device has the following problems: when the assembly device descends through the pressure plate and presses the lithium battery, the conveyor belt cannot provide a good supporting environment for the lithium battery, which causes the pressure applied by the pressure plate on the lithium battery to be unevenly distributed, thereby affecting the assembly operation of the lithium battery. Therefore, we propose a lithium battery processing and assembly device. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a lithium battery processing and assembly device, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: a lithium battery processing and assembly device, including a device body, a conveyor belt group is arranged inside the device body, infrared sensors are arranged on both sides of the device body, a hydraulic cylinder is fixed on the top of the device body, a pressure plate is fixed on the bottom of the telescopic end of the hydraulic cylinder, a supporting device is arranged below the pressure plate, the supporting device includes two cross frames, both of the cross frames are fixed on the inner wall of the device body, a bonding plate is fixed on the top of the two cross frames, the top surface of the bonding plate is in contact with the top of the inner wall of the conveyor belt of the conveyor belt group, strip-shaped protrusions are arranged on both sides of the top of the bonding plate, and the strip-shaped protrusions of the bonding plate are in contact with the outer wall of the conveyor belt of the conveyor belt group, the bonding plate will support the top of the inner wall of the conveyor belt of the conveyor belt group, thereby providing a good supporting environment for the downward pressing assembly operation of the lithium battery.

[0007] The two L-shaped rods are fixed on both sides of the telescopic end of the hydraulic cylinder, and the bottom of the two L-shaped rods are slidably installed with sliders, and a spring 1 is provided between the slider and the L-shaped rod, and the bottom of the slider is hinged with an articulated rod 1, and the end of the articulated rod 1 away from the slider is hinged to the top of the clamping plate. At the same time, each time the telescopic end of the hydraulic cylinder moves downward, the telescopic end of the hydraulic cylinder will drive the L-shaped rod and the slider to move downward, and the slider will first push the articulated rod 1 to drive the clamping plate to move toward the center of the pressure plate, so that the two clamping plates push the lithium battery on the conveyor belt of the conveyor belt group to a position directly below the pressure plate.

[0008] According to the above technical solution, elastic retractable plates are fixed on the sides of the tops of the two clamps that are close to each other. When the two clamps push the lithium battery on the conveyor belt of the conveyor belt group to move, the two clamps will drive the elastic retractable plates to contact the outer wall of the lithium battery.

[0009] According to the above technical solution, a spacing device is provided on one side of the U-shaped frame, and the spacing device includes an elastic telescopic column and two elastic telescopic rods, the two elastic telescopic rods are respectively slidably installed on both sides of the top of the device body, a connecting rod is fixed between the tops of the telescopic ends of the two elastic telescopic rods, an L-shaped push plate is fixed on the side of the connecting rod close to the U-shaped frame, and the telescopic ends of the two elastic telescopic rods are hinged on the sides away from each other with hinged rod 2, and one end of the hinged rod 2 away from the elastic telescopic rod is hinged at the outer wall of the device body, the fixed end of the elastic telescopic column is fixed at the outer wall of the hydraulic cylinder, and the telescopic end of the elastic telescopic column is fixed in the middle of the connecting rod. Each time the telescopic end of the hydraulic cylinder moves downward, the telescopic end of the hydraulic cylinder drives the telescopic end of the elastic telescopic rod to move downward through the elastic telescopic column and the connecting rod. Since the movement trajectory of the elastic telescopic rod is restricted by the hinged rod 2, the elastic telescopic rod as a whole will also move along the top of the device body away from the U-shaped frame during the downward movement of the telescopic end of the elastic telescopic rod. During this process, the L-shaped push plate will move downward with the telescopic end of the elastic telescopic rod, and the L-shaped push plate will move in the direction away from the U-shaped frame. When the L-shaped push plate moves downward, it will pass over the top surface of the lithium battery. When the L-shaped push plate moves in the direction away from the U-shaped frame, it will push the lithium battery that is not under the pressure plate away from the pressure plate.

[0010] According to the above technical solution, the spacing device also includes a square groove block, which is fixed at the top of the fixed end of the elastic telescopic column, and a square rod is horizontally penetrated and slidably installed on the outside of the square groove block, and a Z-shaped baffle is fixed on the side of the square rod away from the U-shaped frame, and a spring 2 is provided between the Z-shaped baffle and the square groove block, and the transverse support plate of the Z-shaped baffle is in the same horizontal plane as the bottom of the connecting rod. At the same time, when the telescopic end of the hydraulic cylinder drives the elastic telescopic column to move downward, the elastic telescopic column will drive the Z-shaped baffle to move downward through the square groove block and the square rod. When the L-shaped push plate pushes the lithium battery that is not under the pressure plate, the lithium battery contacts the Z-shaped baffle, so that the Z-shaped baffle forms a support for the outer wall of the lithium battery.

[0011] According to the above technical solution, an anti-foreign matter device is arranged on the inner side of the conveyor belt of the conveyor belt group, and the anti-foreign matter device includes a notch box, and the notch box is fixed at the inner wall of the device body, and a notch is opened on the side of the notch box away from the U-shaped frame, and a scraper is fixed at the inner wall of the notch box, and the scraper is in contact with the top of the inner wall of the conveyor belt of the conveyor belt group. When the conveyor belt of the conveyor belt group is operating, the scraper will scrape foreign matter and impurities adhered to the top of the inner wall of the conveyor belt of the conveyor belt group into the notch box.

[0012] According to the above technical solution, a connecting plate is fixedly installed at the bottom of the notch box by means of three springs, and L-shaped limit rods are fixed at the four corners of the connecting plate, and the L-shaped limit rods are slidably installed on the outside of the notch box, and annular grooves are provided on both sides of the conveyor belt of the conveyor belt group. The ends of the four L-shaped limit rods away from the connecting plate are respectively slidably installed in the inside of the annular grooves on both sides of the conveyor belt of the conveyor belt group. At the same time, under the action of the three elastic forces of the springs corresponding to the connecting plate, the connecting plate pulls the conveyor belt of the conveyor belt group through the L-shaped limit rod to fit closely with the scraper.

[0013] The present invention provides a lithium battery processing and assembly device, which has the following beneficial effects:

[0014] (1) The present invention sets a supporting device so that the bonding plate supports the top of the inner wall of the conveyor belt of the conveyor belt group, thereby providing a good supporting environment for the downward pressing assembly operation of the lithium battery, thereby avoiding the problem that the pressure exerted by the pressing plate on the lithium battery is unevenly distributed, affecting the assembly of the lithium battery. The strip-shaped protrusions of the bonding plate contact the outer wall of the conveyor belt of the conveyor belt group, so that the bonding plate can effectively control the position of the conveyor belt of the conveyor belt group, ensuring that the conveyor belt of the conveyor belt group does not deviate or slide laterally during operation; at the same time, the hydraulic cylinder, L-shaped rod, slider, hinged rod 1, clamping plate, and pressing plate cooperate to drive the two clamping plates to push the lithium battery on the conveyor belt of the conveyor belt group to the position directly below the pressing plate, thereby ensuring that the pressing plate When pressing down, it can accurately act on the center of the lithium battery, avoiding the uneven pressing caused by misalignment or offset of the lithium battery, thereby improving the accuracy of the lithium battery assembly operation. At the same time, the two clamps drive the elastic telescopic plate to contact the outer wall of the lithium battery. At this time, when the pressing plate moves downward, it will first contact the top of the telescopic end of the elastic telescopic plate. As the pressing plate continues to move downward, the pressing plate pushes the telescopic end of the elastic telescopic plate to expand and contract until the pressing plate contacts the top of the lithium battery and presses down to assemble the lithium battery. The elastic telescopic plate plays a buffering role when the pressing plate continues to press down, which helps to reduce the impact force generated when the pressing plate directly contacts the lithium battery, and can effectively prevent the lithium battery from being subjected to sudden strong impact, reducing the risk of battery damage or deformation.

[0015] (2) The present invention sets a spacing device so that the hydraulic cylinder, elastic telescopic column, connecting rod, elastic telescopic rod, and hinged rod cooperate to drive the L-shaped push plate to push the lithium battery that is not under the pressure plate away from the pressure plate, thereby avoiding the problem that the lithium battery at the edge of the pressure plate will interfere with or affect the operation of the pressure plate, thereby improving the accuracy of the pressure plate when pressing down the lithium battery for assembly, and reducing problems caused by unnecessary contact or misoperation; at the same time, the hydraulic cylinder, elastic telescopic column, square groove block, square rod, and Z-shaped baffle cooperate to drive the Z-shaped baffle to support the outer wall of the lithium battery, thereby avoiding the problem that the lithium battery falls over after the L-shaped push plate pushes the lithium battery excessively, affecting the subsequent lithium battery pressing down assembly operation.

[0016] (3) The present invention sets an anti-foreign matter device so that the scraper can scrape foreign matter and impurities adhered to the top of the inner wall of the conveyor belt of the conveyor belt group into the notch box, thereby avoiding the problem of foreign matter and impurities sneaking into the gap between the bonding plate and the conveyor belt of the conveyor belt group, causing the conveyor belt of the conveyor belt group to be abnormally bulged locally, thereby ensuring that the conveyor belt of the conveyor belt group can stably transmit lithium batteries; at the same time, under the action of the three elastic forces of the spring corresponding to the connecting plate, the connecting plate pulls the conveyor belt of the conveyor belt group to fit tightly with the scraper through the L-shaped limit rod, thereby facilitating the scraper to scrape foreign matter and impurities embedded in the conveyor belt of the conveyor belt group into the notch box, thereby improving the effect of the scraper in removing foreign matter and impurities adhered to the top of the inner wall of the conveyor belt of the conveyor belt group.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] See also Figure 1 - Figure 8 One embodiment of the present invention is: a lithium battery processing and assembly device, including a device body 1, a conveyor belt group 3 is arranged inside the device body 1, infrared sensors 2 are arranged on both sides of the device body 1, a hydraulic cylinder 5 is fixed on the top of the device body 1, a pressing plate 6 is fixed at the bottom of the telescopic end of the hydraulic cylinder 5, and a supporting device 7 is arranged below the pressing plate 6. The supporting device 7 includes two cross frames 71, and the two cross frames 71 are fixed on the inner wall of the device body 1. The top of the two cross frames 71 is fixed with a bonding plate 72, and the top surface of the bonding plate 72 is in contact with the top of the inner wall of the conveyor belt of the conveyor belt group 3. Through the arrangement of the above structure, the bonding The plate 72 will support the top of the inner wall of the conveyor belt of the conveyor belt group 3, thereby providing a good support environment for the downward pressing assembly operation of the lithium battery, thereby avoiding the problem that the pressure applied by the pressing plate 6 on the lithium battery will be unevenly distributed, affecting the assembly of the lithium battery. Strip-shaped protrusions are provided on both sides of the top of the bonding plate 72, and the strip-shaped protrusions of the bonding plate 72 are in contact with the outer wall of the conveyor belt of the conveyor belt group 3. Through the contact between the strip-shaped protrusions of the bonding plate 72 and the outer wall of the conveyor belt of the conveyor belt group 3, the bonding plate 72 can effectively control the conveyor belt position of the conveyor belt group 3 to ensure that the conveyor belt of the conveyor belt group 3 does not deviate or slide laterally during operation.

[0028] The support device 7 also includes two L-shaped rods 75 and two U-shaped sliding rods 73. The two U-shaped sliding rods 73 are slidably mounted on both sides of the bottom of the bonding plate 72. The tops of the two U-shaped sliding rods 73 are close to each other and are fixed with clamping plates 77. The bottom surfaces of the clamping plates 77 contact the top surfaces of the conveyor belts of the conveyor belt group 3. The two L-shaped rods 75 are fixed on both sides of the telescopic ends of the hydraulic cylinder 5. Slide blocks 76 are slidably mounted on the bottoms of the two L-shaped rods 75, and a spring 1 is provided between the slide block 76 and the L-shaped rod 75. The bottom of the slide block 76 is hinged with an articulated rod 1 74, and one end of the articulated rod 1 74 away from the slide block 76 is hinged to the top of the clamping plate 77. Through the arrangement of the above structure, the two clamping plates 77 push the lithium batteries on the conveyor belt of the conveyor belt group 3 to move to a position just below the pressing plate 6, thereby ensuring that the pressing plate 6 can accurately act on the center of the lithium battery when pressing down, avoiding the uneven downward pressure caused by misalignment or offset of the lithium battery, thereby improving the accuracy of the lithium battery assembly operation.

[0029] An elastic expansion plate 78 is fixed to the side of the tops of the two clamping plates 77 that are close to each other. Through the arrangement of the above structure, the elastic expansion plate 78 plays a buffering role when the pressure plate 6 continues to press down, which helps to reduce the impact force generated when the pressure plate 6 directly contacts the lithium battery, and can effectively prevent the lithium battery from being subjected to sudden strong impact, reducing the risk of battery damage or deformation.

[0030] A spacing device 8 is provided on one side of the U-shaped frame 4, and the spacing device 8 includes an elastic telescopic column 85 and two elastic telescopic rods 81. The two elastic telescopic rods 81 are respectively slidably installed on both sides of the top of the device body 1, and a connecting rod 83 is fixed between the tops of the telescopic ends of the two elastic telescopic rods 81. An L-shaped push plate 84 is fixed on the side of the connecting rod 83 close to the U-shaped frame 4. The telescopic ends of the two elastic telescopic rods 81 are hinged on the side away from each other with a hinge rod 2 82, and the end of the hinge rod 2 82 away from the elastic telescopic rod 81 is hinged at the outer wall of the device body 1, the fixed end of the elastic telescopic column 85 is fixed at the outer wall of the hydraulic cylinder 5, and the telescopic end of the elastic telescopic column 85 is fixed at the middle part of the connecting rod 83. Through the arrangement of the above structure, the L-shaped push plate 84 pushes the lithium battery that is not under the pressure plate 6 away from the pressure plate 6, thereby avoiding the problem that the lithium battery is at the edge of the pressure plate 6 and causing interference or influence on the operation of the pressure plate 6, thereby improving the accuracy of the pressure plate 6 when pressing down the lithium battery for assembly, and reducing the problems caused by unnecessary contact or misoperation.

[0031] The spacer 8 also includes a square groove block 86, which is fixed on the top of the fixed end of the elastic telescopic column 85. A square rod 87 is horizontally penetrated and slidably installed on the outside of the square groove block 86. A Z-shaped baffle 88 is fixed on the side of the square rod 87 away from the U-shaped frame 4. A spring 2 is provided between the Z-shaped baffle 88 and the square groove block 86. The horizontal support plate of the Z-shaped baffle 88 and the bottom of the connecting rod 83 are in the same horizontal plane. Through the arrangement of the above structure, the Z-shaped baffle 88 forms a support for the outer wall of the lithium battery, thereby avoiding the problem that the lithium battery falls over after the L-shaped push plate 84 pushes the lithium battery excessively, affecting the subsequent lithium battery downward pressure assembly operation.

[0032] When in use, the assembled lithium battery is placed on the top of the conveyor belt of the conveyor belt group 3, and then the conveyor belt group 3 is started. The conveyor belt group 3 will transport the lithium battery. When the lithium battery passes the infrared sensor 2, if the lithium battery height is inconsistent, it will block the infrared sensor 2 from irradiating the laser on the sensor sheet corresponding to the infrared sensor 2. Then, the lithium battery group moves to the bottom of the hydraulic cylinder 5, and the telescopic end of the hydraulic cylinder 5 pushes the pressing plate 6 down and presses the lithium battery down. When the lithium battery is pressed down for assembly, the bonding plate 72 will press the inner wall top of the conveyor belt of the conveyor belt group 3. The laminating plate 72 is formed with a support, thereby providing a good support environment for the pressing and assembling operation of the lithium battery, thereby avoiding the problem that the pressure exerted by the pressing plate 6 on the lithium battery is unevenly distributed, which affects the assembly of the lithium battery. The strip-shaped protrusions of the laminating plate 72 are in contact with the outer wall of the conveyor belt of the conveyor belt group 3, so that the laminating plate 72 can effectively control the conveyor belt position of the conveyor belt group 3, ensuring that the conveyor belt of the conveyor belt group 3 does not deviate or slide laterally during operation; at the same time, each time the telescopic end of the hydraulic cylinder 5 moves downward, the telescopic end of the hydraulic cylinder 5 drives the L-shaped rod 75 and the slider When the two clamping plates 77 push the lithium battery on the conveyor belt of the conveyor belt group 3 to move to the position directly below the pressing plate 6, the pressing plate 6 can be ensured to accurately act on the center of the lithium battery when pressing down, thus avoiding the uneven pressing phenomenon caused by the misalignment or offset of the lithium battery, thereby improving the accuracy of the lithium battery assembly operation. At the same time, when the two clamping plates 77 push the lithium battery on the conveyor belt of the conveyor belt group 3 to move, the two clamping plates 77 will The movable elastic expansion plate 78 contacts the outer wall of the lithium battery. At this time, when the pressure plate 6 is pressed down and moved, it will first contact the top of the expansion end of the elastic expansion plate 78. As the pressure plate 6 continues to be pressed down and moved, the pressure plate 6 pushes the expansion end of the elastic expansion plate 78 to expand and contract until the pressure plate 6 contacts the top of the lithium battery and presses down and assembles the lithium battery. The elastic expansion plate 78 plays a buffering role when the pressure plate 6 continues to be pressed down, which helps to reduce the impact force generated when the pressure plate 6 directly contacts the lithium battery, and can effectively prevent the lithium battery from being subjected to sudden strong impact, reducing the risk of battery damage or deformation.

[0033] Each time the telescopic end of the hydraulic cylinder 5 moves downward, the telescopic end of the hydraulic cylinder 5 drives the telescopic end of the elastic telescopic rod 81 to move downward through the elastic telescopic column 85 and the connecting rod 83. Since the movement trajectory of the elastic telescopic rod 81 is restricted by the hinge rod 82, the elastic telescopic rod 81 as a whole will also move along the top of the device body 1 in the direction away from the U-shaped frame 4 during the downward movement of the telescopic end of the elastic telescopic rod 81. During this process, the L-shaped push plate 84 will move downward with the telescopic end of the elastic telescopic rod 81, and the L-shaped push plate 84 will move in the direction away from the U-shaped frame 4. When the L-shaped push plate 84 moves downward, it will pass over the top surface of the lithium battery. When the L-shaped push plate 84 moves in the direction away from the U-shaped frame 4, it will push the lithium battery that is not under the pressure plate 6 away from the pressure plate 6, thereby avoiding the problem that the lithium battery at the edge of the pressure plate 6 will interfere with or affect the operation of the pressure plate 6, and then The accuracy of the pressing plate 6 when pressing down the lithium battery for assembly can be improved, and problems caused by unnecessary contact or misoperation can be reduced; at the same time, when the telescopic end of the hydraulic cylinder 5 drives the elastic telescopic column 85 to move downward, the elastic telescopic column 85 will drive the Z-shaped baffle 88 to move downward through the square groove block 86 and the square rod 87. When the L-shaped push plate 84 pushes the lithium battery that is not under the pressing plate 6, the lithium battery contacts the Z-shaped baffle 88, so that the Z-shaped baffle 88 forms a support for the outer wall of the lithium battery, thereby avoiding the problem that the lithium battery falls over after the L-shaped push plate 84 pushes the lithium battery excessively, affecting the subsequent lithium battery pressing down assembly operation. It should also be noted that when there are too many lithium batteries between the Z-shaped baffle 88 and the L-shaped push plate 84, the push of the Z-shaped baffle 88 will drive the square rod 87 to move laterally along the inside of the square groove block 86, and the spring 2 between the Z-shaped baffle 88 and the square groove block 86 is stretched.

[0034] See also Figure 1 - Figure 8 Based on the above embodiment, in another embodiment of the present invention, a foreign body prevention device 9 is provided inside the conveyor belt of the conveyor belt group 3.

[0035] The anti-foreign matter device 9 includes a notch box 91, which is fixed on the inner wall of the device body 1. A notch is provided on the side of the notch box 91 away from the U-shaped frame 4. A scraper 92 is fixed on the inner wall of the notch box 91. The scraper 92 contacts the top of the inner wall of the conveyor belt of the conveyor belt group 3. Through the arrangement of the above structure, the scraper 92 will scrape foreign matter and impurities adhered to the top of the inner wall of the conveyor belt of the conveyor belt group 3 into the notch box 91, thereby avoiding foreign matter and impurities from entering between the bonding plate 72 and the conveyor belt of the conveyor belt group 3, resulting in the problem of local abnormal bulge of the conveyor belt of the conveyor belt group 3, thereby ensuring that the conveyor belt of the conveyor belt group 3 can stably transmit lithium batteries.

[0036] A connecting plate 94 is fixedly installed at the bottom of the notch box 91 by spring three, and L-shaped limit rods 93 are fixed at the four corners of the connecting plate 94, and the L-shaped limit rods 93 are slidably installed on the outside of the notch box 91, and annular grooves are opened on both sides of the conveyor belt of the conveyor belt group 3. The ends of the four L-shaped limit rods 93 away from the connecting plate 94 are respectively slidably installed in the inside of the annular grooves on both sides of the conveyor belt of the conveyor belt group 3. Through the arrangement of the above structure, the L-shaped limit rods 93 pull the conveyor belt of the conveyor belt group 3 to fit tightly with the scraper 92, thereby facilitating the scraper 92 to scrape foreign matter and impurities embedded in the conveyor belt of the conveyor belt group 3 into the notch box 91, thereby improving the effect of the scraper 92 in removing foreign matter and impurities adhering to the top of the inner wall of the conveyor belt of the conveyor belt group 3.

[0037] During use, when the conveyor belt of the conveyor belt group 3 is operating, the scraper 92 will scrape foreign matter and impurities adhered to the top of the inner wall of the conveyor belt of the conveyor belt group 3 into the notch box 91, thereby avoiding the foreign matter and impurities from sneaking into the gap between the bonding plate 72 and the conveyor belt of the conveyor belt group 3, causing the problem of local abnormal bulge of the conveyor belt of the conveyor belt group 3, thereby ensuring that the conveyor belt of the conveyor belt group 3 can stably transmit lithium batteries; at the same time, under the action of the three elastic forces of the spring corresponding to the connecting plate 94, the connecting plate 94 pulls the conveyor belt of the conveyor belt group 3 to fit tightly with the scraper 92 through the L-shaped limit rod 93, thereby facilitating the scraper 92 to scrape foreign matter and impurities embedded in the conveyor belt of the conveyor belt group 3 into the notch box 91, thereby improving the effect of the scraper 92 in removing foreign matter and impurities adhered to the top of the inner wall of the conveyor belt of the conveyor belt group 3.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
